The Planets & Dwarf Planets
Planetary Reports are generated by "TheSky" software. 
(http://www.ki0ar.com/planrpts.html) These reports provide predicted data for 
the planets on the first of each month for the current year. The rise and set 
times for the Sun and the Moon for each day of the month are also included in 
the reports. These reports have been optimized for the Denver, Colorado 
location, however, the times will be approximate for other locations on Earth.


(All times are local unless otherwise noted.)


* Planetary Highlights for September - Begin September with a glimpse of Saturn 
before it disappears into the twilight glow. Continue your evening viewing with 
Mars and Venus. Jupiter rises about the same time that Saturn sets. Jupiter 
makes its best appearance in almost 50 years. Uranus also lies within 2° of 
Jupiter and should still be relatively easy to spot. Mercury puts in a brief 
appearance in the morning sky just before sunrise.


* Mercury - Is in inferior conjunction on the 3rd. Mercury is at greatest 
western elongation (18° above the eastern horizon) on the 19th. Mercury rises 
at 6:55 a.m. on the 1st and about 5:54 a.m. by month's end. Look for Mercury in 
the morning sky about mid-month. Mercury moves from the constellation of 
Sextans into Virgo this month shining at magnitude 0.5.


* Venus - Is at its greatest brilliancy on the 23rd, magnitude -4.8. Venus is 
visible in the west soon after sunset. Venus sets at 9:02 p.m. on the 1st and 
about 7:33 p.m. by month's end. Venus is in the constellation of Virgo this 
month.


* Earth - The Autumnal Equinox occurs at 11:09 p.m. EDT on the 22nd.


* Mars - Sets at 9:09 p.m. on the 1st and about 7:33 p.m. by month's end. Mars 
keeps pace with Venus all month, so watch our nearest planetary neighbors 
within a few degrees of each other all month long. Mars is in the constellation 
of Virgo this month shining at magnitude 1.5.


* Jupiter - Is at opposition on the 21st, rising as the Sun sets. Jupiter rises 
is 8:21 p.m. on the 1st and about 6:14 p.m. by month's end. Jupiter rises about 
the same time as Saturn sets this month. Look for Jupiter in the east and south 
in the evening and late evening. Jupiter is in the constellation of Pisces this 
month shining at magnitude -2.9.


* Saturn - Is in conjunction with the Sun on the 30th. Saturn rapidly 
disappears into the evening twilight glow as the month progresses, so catch a 
glimpse of Saturn soon after sunset during the first half of the month. Saturn 
sets at 8:38 p.m. on the 1st and about 6:48 p.m. by month's end. Look for 
Saturn in the evening low in the west after sunset. Saturn is in the 
constellation of Virgo shining at magnitude 1.0.


* Uranus - Is at opposition on the 21st, rising as the Sun sets. This month, 
Uranus remains even closer to Jupiter than it did last month, less than 1° 
north of Jupiter. Uranus rises at 8:14 p.m. on the 1st and about 6:13 p.m. by 
month's end, preceding Jupiter by just a few minutes all month. Uranus is in 
the constellation of Pisces shining at magnitude 5.7.


* Neptune - Rises at 6:54 p.m. on the 1st and about 4:54 p.m. by month's end. 
Neptune will be well above the eastern horizon by sunset this month making it a 
little easier to spot in the evening sky. Neptune is in the constellation of 
Capricornus this month shining at magnitude 7.8.


Dwarf Planets  
* Ceres - Sets at 11:01 p.m. on the 1st and about 9:27 p.m. by month's end. 
Ceres moves into the constellation of Sagittarius this month shining at 
magnitude 8.8. 


* Pluto - Sets at 1:28 a.m. on the 1st and about 11:26 p.m. by month's end. 
Pluto is in the constellation of Sagittarius shining at magnitude 14.0.


As always, good luck at spotting these two, a large telescope and dark skies 
will be needed.


-----------------------------------------------------------


Astronomical Events


Meteor Showers
* No significant meteor shower activity this month, but you can expect to see 
from 1 to 6 meteors per hour early in the month.


* For more information about Meteor Showers, visit Gary Kronk's Meteor Showers 
Online web page at http://meteorshowersonline.com/.


Comets
* "Comet 103P/Hartley could hit the headlines in the next 2 months. First, the 
comet comes closest to both the Sun and Earth in October's second half, when 
observers should get nice views through binoculars and telescopes and might 
glimpse it with naked eyes. Then, in early November, NASA's Deep Impact 
spacecraft will fly past the comet.


Currently, Comet Hartley is brightening quickly as it approaches Earth. 
Astronomers expect it to reach 10th magnitude by late September. The best views 
will come under a dark sky starting around the 24th. The comet then lies in 
Cassiopeia, south of that constellation's familiar W-shaped asterism, and 
remains visible all night." (from Astronomy Magazine, September 2010, P. 42.)

page at http://cometography.com/.


Eclipses
* No eclipse activity this month.


Observational Opportunities
* Jupiter appears at its best and brightest than it has since 1963 on the 
evening of the 21st. Jupiter will shine at magnitude -2.9 and subtends about 
49.9 seconds of arc.


* While observing Jupiter, scan the nearby sky with a good pair of binoculars 
and spot Uranus within 1° north of Jupiter.


Asteroids (From west to east)
* Flora is at opposition on the 10th in the constellation of Aquarius.
* Laetitia is at opposition on the 14th in the constellation of Pisces.
* Hebe is at opposition on the 21st in the constellation of Cetus.
* Iris is in the constellation of Gemini.

Planetary/Lunar Exploration Missions
(Excerpts from recent mission updates)


* Cassini - Aug. 26, 2010
Cassini Significant Events 08/18/10 - 08/24/10


"Wednesday, August 18 (DOY 230)
Today marked the 11th anniversary of Cassini's Earth flyby.


Friday, August 20 (DOY 232)
Spacecraft Operations (SCO) successfully completed real time commanding to load 
Command & Data Subsystem (CDS) flight software (FSW) V10.0 patches. This is the 
last planned software update for CDS FSW for the remainder of the Cassini 
Mission. The command loss timer will be set back to 110 hours on Sunday.


SCO completed the first long reaction wheel rest period during the CDS FSW 
uplink and checkout period. The objective for these wheel rest periods is to 
allow for a redistribution of lubricants within the bearing assemblies. Bearing 
consultants have recommended this approach to mitigate against increased 
friction in the bearings, but at this point there is still insufficient data to 
judge the effectiveness of this plan. Attitude control was switched from 
reaction wheels to thrusters on Aug. 18, and switched back to wheels today.


Monday, August 23 (DOY 235)
The Science Forum for S66 was held today. Topics included an overview of 
science planned for this sequence followed by highlights, unique activities, 
and highest priority observations as described by the Target Working Team (TWT) 
and Orbiter Science Team (OST) leads, with comments from the Investigation 
Scientists and other instrument team representatives.


Tuesday, August 24 (DOY 236)
This week the Radio Science team performed an operational readiness test with 
the DSN in preparation for the occultation observation on Sept. 2. The 
Magnetospheric and Plasma Science instruments performed an 11.5 hour survey. 
The Composite Infrared Spectrometer performed an 8 hour spectroscopic 
observation of the infrared star CW Leonis. The Cosmic Dust Analyzer continued 
its interstellar dust campaign."

* New Horizons - No new news since July 27, 2010
LORRI Looks Back at "Old Friend" Jupiter


"In early 2007 New Horizons flew through the Jupiter system, getting a 
speed-boost from the giant planet's gravity while snapping stunning, close-up 
images of Jupiter and its largest moons.


Fast forward to 2010 and New Horizons has given us another glimpse of old 
friend Jupiter, this time from a vantage point more than 16 times the distance 
between Earth and the Sun, and almost 1000 times as far away as when New 
Horizons reconnoitered Jupiter. While the planet is too far for the camera to 
pick up the swirling clouds and brewing, Earth-sized storms it saw just three 
years ago, "the picture is a dramatic reminder of just how far New Horizons, 
moving about a million miles a day, has traveled," says mission Principal 
Investigator Alan Stern, of the Southwest Research Institute.

ninth planet - visit the New Horizons home page: http://pluto.jhuapl.edu/.


* Dawn - No new news since June 29, 2010
Engineers Assess Dawn's Reaction Wheel


"Engineers are studying the reaction wheels on NASA's Dawn spacecraft after 
automatic sensors detected excess friction building up in one of them and 
powered it off early on the morning of June 17, 2010. Reaction wheels spin to 
help a spacecraft maintain attitude control, and Dawn, which is exploring the 
asteroid belt, uses three wheels in normal operations.


The three other reaction wheels are functioning normally. Mission managers said 
plans for Dawn to visit the asteroid Vesta in 2011 and 2012 and dwarf planet 
Ceres in 2015 will not be not affected."

http://www.nasa.gov/mission_pages/dawn/main/index.html.


* MESSENGER - August 17, 2010
Vulcanoid Search Continues as MESSENGER Reaches Orbital Perihelion


"Today MESSENGER will pass within 0.308 astronomical units (AU) of the Sun (one 
AU is Earth’s distance from the Sun, approximately 150 million kilometers or 93 
million miles), providing MESSENGER scientists with another opportunity to 
search for vulcanoids. Named after the hypothetical planet Vulcan, whose 
existence was disproven in 1915, vulcanoids are asteroids that orbit the Sun 
inside the orbit of the planet Mercury. 


No vulcanoids have yet been discovered, and it is not known if any exist. But 
should they be found, these small, rocky asteroids may yield insights into the 
formation and early evolution of the solar system. They might contain material 
left over from the earliest period of planet formation and help determine the 
conditions under which the terrestrial planets, particularly Mercury, formed. 
Vulcanoids would also represent an additional population of impactors that 
contributed to the cratering history of Mercury much more than that of any 
other body. Impacts by vulcanoids would make the planet's surface appear older, 
relative to the surfaces of the Moon and other inner planets, than it actually 
is."

Mars Missions


* Mars Odyssey Orbiter - No new news since July 23, 2010
NASA Spacecraft Camera Yields Most Accurate Mars Map Ever


"PASADENA, Calif. - A camera aboard NASA's Mars Odyssey spacecraft has helped 
develop the most accurate global Martian map ever. Researchers and the public 
can access the map via several websites and explore and survey the entire 
surface of the Red Planet.
The map was constructed using nearly 21,000 images from the Thermal Emission 
Imaging System, or THEMIS, a multi-band infrared camera on Odyssey. Researchers 
at Arizona State University's Mars Space Flight Facility in Tempe, in 
collaboration with NASA's Jet Propulsion Laboratory in Pasadena, Calif., have 
been compiling the map since THEMIS observations began eight years ago.


The pictures have been smoothed, matched, blended and cartographically 
controlled to make a giant mosaic. Users can pan around images and zoom into 
them. At full zoom, the smallest surface details are 100 meters (330 feet) 
wide. While portions of Mars have been mapped at higher resolution, this map 
provides the most accurate view so far of the entire planet.


The new map is available at: 
http://www.mars.asu.edu/maps/?layer=thm_dayir_100m_v11.";


"A simulated fly-through using the newly assembled imagery is available online 
at http://www.nasa.gov/mission_pages/mars/missions/odyssey/20060313.html.


The fly-through plus tools for wandering across and zooming into the large 
image are at http://themis.asu.edu/.";

* Mars Exploration Rover Mission (Spirit and Opportunity) - August 25, 2010


SPIRIT UPDATE: Spirit Remains Silent at 'Troy' - sols 2356-2361, August 19-24, 
2010:


"Spirit remains silent at her location on the west side of Home Plate. No 
communication has been received from the rover since Sol 2210 (March 22, 2010).


It is likely that Spirit has experienced a low-power fault and has turned off 
all sub-systems, including communication and gone into a deep sleep, trying to 
recharge her batteries. There is the additional risk that the rover may trip a 
mission clock fault. To respond to either case, the project is both listening 
for Spirit with the Deep Space Network and Mars Odyssey orbiter for autonomous 
recovery communication from the low-power fault case, and conducting a "Sweep & 
Beep" strategy to stimulate the rover in the case of a mission clock fault.


Although power levels are estimated to be improving with the advancing 
springtime in the southern hemisphere of Mars, atmospheric conditions 
historically deteriorate (higher atmospheric opacity) at this time. So, a 
response from Spirit is still not expected for some time.


Total odometry is unchanged at 7,730.50 meters (4.80 miles)."


OPPORTUNITY UPDATE: Opportunity Stops to Check Out Rocks - sols 2336-2341, 
August 19-25, 2010:


"Opportunity has paused in her trek toward Endeavour crater to examine an 
exposed outcrop of rock that is of interest to the science team.


On Sol 2336 (Aug. 19, 2010), the rover performed a 7-meter (23-foot) backward 
turn with a forward bump to approach the outcrop contact. On the next sol, 
Opportunity performed a short turn to place surface targets within reach of the 
robotic arm (Instrument Deployment Device, IDD). On Sol 2339 (Aug. 23, 2010), 
Opportunity conducted a relay test pass with Mars Express as part of a regular 
checkout of the Mars Express relay. On the next sol, the rover used the robotic 
arm to collect a microscopic imager (MI) mosaic of a surface target, called 
"Clarin Beach," which was followed by a placement of the alpha particle X-ray 
spectrometer (APXS) on the same target for integration. On Sol 2341 (Aug. 25, 
2010), Opportunity continued the investigation of this outcrop contact, 
collecting another set of microscopic imager mosaics of new targets and then a 
placement of the APXS on a target called "Duero Beach."


As of Sol 2340 (Aug. 24, 2010), solar array energy production was 562 
watt-hours with atmospheric opacity (Tau) of 0.334 and the solar array dust 
factor of 0.7285.


Total odometry as is 22,647.85 meters (22.65 kilometers, or 14.07 miles)."
